TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM L. HALLnn, of Carlisle, lin the county of Cumberland,A and Stute of Pennsylvania, have invented a new and useful Improvement in. Fruit Jars; andjI do hereby declare the following to be a full, clear,v and exact description of the same, reference being h ad'to the accompanying drawings, which are made part of this specification, andlwhich representa longitudinal centrul'scetion oi'- a fruit jar embodying my invention.

The subject of my invention is a glass fruit jar,'having a. conical neck and glass cap, whose interior is shaped in conformity with the neck, so that a rubber ring on'` thc outside of the neck may bc tightly wedged between Athe latter and thc cap, in order to adnptthc cap to be snugly applied, and prevent the admissionv of air to the interior of the' jar. From a casual observation the jar, the subject; of 'this invention, bears n. close resemblance tog'sorne which have previously been devised, but a careful perusal of the following description will show it to comprise peculiarities which distinguish it from all others, and render it a. more eiicient article.

A. represents a glass jar, formed with a conical or" upwardly-tapering neck A', which terminates at top in a". bead or projection, a, which forms a shoulder to ferm a bearing for the ring or gasket B, and prevent 'the latter slipping o' at the top. C is a cap, which is composed of glass, and while covering the tp of the jar cx tends downward so as' to embrace the outside of the neck. The interior of the lcap C is made tapering, to correspond with the conical form of theneek A. Heretofcre the use ot'v glass caps embracing the neck ofthe jar has been attended with considerable difiiculty for this reasonrthe neckV oi' the jar, as a generalthing, is made slightly elliptical'i'st'end' of`circular, requirin'gto beublo'wrr and ground to'adapt the cap to be snug-ly tted upon it. This nishing of the neck I accomplish by means of a' tool, whereby the same maybe shaped so as to cicct a fit between it and the cap. This finishing is not to be regarded as a feature of my invention, but it is mentioned as a simpler and cheaper modo, and in order that the mode of constructing lthe jar may bel fully understood. On the inside of the cap C is formed a shoulder, al, and a groove, a". To close the jar them-ing B is iirst placed around the neck in contact with the shoulder'a, and the ca'p C is forced down o'ver thc ring, so as to wedge tho latter tightly between the cap and the neck of the jar. The mov/ementl of the cap relatively to the ring is arrested by the ring coming in contact with the shoulder a1, when the further depression of, the cop causes the top of the neck to enter Vand occupy the groove a1, whereby the true position of the cap is insured. The fruit is placed in the jar in a somewhat heated condition, so that whenit cools there will be formed a vacuum between the fruit and the cap, air being excluded by the rubber ring. .The external pressure of the atmosphere upon the cap then aids the ring in preventing the displacement of said cap.

- I am aware that it is not now to use a gloss cap in connection with ajax' whose neck is partially embraced thereby, but I know of no previous instance where the embracing gloss cap has been used in connection with a conicahneck, the latter to secure the ring B, which holds on the cap, and also excludes air from the jar. The

jar may be opened by insertingia knife',A blade, or a device made especially for the purpose, betweenl the ring B and the neck, so as to ,admit air into the jar, after which the cap can be readily taken olf.

I Having thus described my invention, the following is what I claim as new herein, and desire to secure by Letters Patenti' .I claim a glass jar haviuga conical neck having a rubber ring, movable on its exterior, and 'depressed by the shoulder a1 of the lid C, whose groove, a, in combination with the lip' a, forms a nearly tight joint to keep the fruitfi'om contact with the rubber, the whole arranged substantially as described and represented.

The above specification of my improvement in fruit jars'signed this 12th day of July, 11865.-
